Plaxico Burress’ teammate, Antonio Pierce, who was with him at a Manhattan club when he shot himself in the leg with an illegal gun, and the doctor who treated Burress for the gunshot wound, are expected to tell cops today what they know about the accident and hospital coverup.

Pierce, who took Burress’ .40-caliber Glock to his own New Jersey home after getting his teammate to the hospital, will speak to police with his lawyer, Michael Bachner, sources said.

Bachner yesterday said Pierce did not know Burress was packing heat when they went to the Latin Quarter until the gun went off as Burress fumbled with it.

Dr. Josyann Abisaab, the New York-Cornell Hospital doctor who attended to Burress, will be accompanied by her own lawyer when cops interview her.

That lawyer, Barry Bohrer, could not be reached for comment.

Abisaab, 44, was suspended by New York-Cornell, which has said it is investigating why staff did not promptly tell police they were treating a gunshot victim as required by state law.

The hospital, which admitted Burress under the alias “Harris Smith,” has said other people could be disciplined.

State law mandates that the attending physician or hospital management must immediately report treating gunshot wounds.

A law-enforcement source yesterday suggested that someone at the hospital other than Abisaab might have been responsible for calling cops that night.

“Do you really expect a doctor to make that call?” asked the source, suggesting that an administrative person, other than a physician busy with a bleeding patient, would be better suited to contacting police.

Sources have said Abisaab spent just a brief time with Burress, who remained in the hospital for 11 hours.
